Description
The 1320 is a versatile unit, with a wide selection of user programmable capabilities, for testing or evaluation of inductor characteristics with a DC bias current applied.
High DC Bias Current: Offers flexibility with programmable DC current from 0 – 20A, forward or reverse biasing. Up to 5 units can be connected in parallel to extend the current range to a maximum of 100A
Forward and Reverse: Biasing A unique feature of the 1320 allows the operator to select bias current direction as forward or reverse. This has the advantage of testing hysteresis effects on inductors without changing test leads.
Display of Choice: The 1320 provides the ability to select display of DC bias current, DC resistance value or DC voltage across the device, enabling the user to select the parameter or test results of primary interest.
Setup Storage and Recall: The user friendly front panel of the 1320 makes for fast, easy setup of test conditions for 50 test groups which can be stored and recalled from internal memory to ensure that tests can be run the same way each time. Each group can contain up to 21 steps for performing multi-point testing at various levels of current.
Multi-point Current Testing: The 1320 can be programmed for multi-point current testing with measurements being made at stepped current levels or as a loop test (current stepped up and back down). This makes it possible to evaluate devices under varying or actual operating conditions.
Connection to LCR Meters: The unit can be used in conjunction with QuadTech or other LCR meters for applying an external DC bias current to the device under test. The 1320 is connected directly to the bridge’s 4-terminal Kelvin connections and enhances the measurement capability of existing instrumentation.
